The other two commits of this PR are already in our codebase. See https://github.com/Bitcoin-ABC/ElectrumABC/commit/590e532f26c73b1568eaef20b011099e9da9c35a
The `RecoveryDeviceType` enum is not used for now because there is an API breakage between trezor 0.13.8 and 0.13.9 (D16406). We can directly switch to using `RecoveryDeviceInputMethod` after we drop support for 0.13.8
